Sammy-Jane and Yvonne, dressed in a smart blue suit and a black dress respectively, take a short, uneventful walk acros the silt pond until Yvonne suddenly sinks knee-deep, overbalances, and is covered as far up as her boobs in the mud. Sammy-Jane laughs at her predicament as Yvonne extracts herself from the deep ooze. Soon, the roles are reversed, as Yvonne has the laugh when Sammy-Jane takes one wrong step and sinks to her crotch in a single graceful slip. She too struggles free of the mire, and they both engage in horseplay, covering each other gradually in the sloppy clay. They sit on the banks and slide into the channels. Yvonne removes her boots which are becoming troublesome, and Sammy-Jane follows suit. They play around, running and jumping into the softer mud, splashing it about. After a little more mucking about, they strip out of their clothes to display equally mud-covered bodies.
